INDICATOR.

Speccat'ion'of Letters Patent.

Application filed May 29, 1913. Serial N0. 770,687.

To alli/whom it may concern 'Be it known that I, MICHAEL F. SULLI- van, a citizen of the United States of .America, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and usef vide an indicator which is le and cheap of construction and accurate n operation;A

to provide an indicator with automatic means for changing the display on the indica'tor .face'yat any predetermined points along the route of travel; to provide simple and efficient means for resetting said indicator. y

With these and such other objects in view as may hereinafter more fully appear, my device consists in the novel arrangement and construction of/part's hereinafter more fully described and claimed, and which are shown in the accompanying drawings, wherein-,-

Figure 1 is a perspective View of a car truck with the motor-wheel for the indicator attached thereto. Fig. 2 is a. perspectivevie'w of the indicator, the casing being removed.

Referring to said drawings by numerals,

a car truck 1 has fastened thereto in any suitable and convenient manner a bracket 2, the arm of said bracket being hinged at 3 and vcarryiny at its outer extremity, the enlarged cylin Pr'ical portion e bored throughout its len th to form a journal for the. shaft 5 o the motor or drive-wheel 6.

A The purpose of the hinge 3 in the arm of the side wall of the casing or cover.

bracket 2 is to allow for inequalities due to the rise 'and Afall of the truck 1 caused by the roughness of the road bed;

Fasteiiedto shaft 5, and constrained to turn therewith, is a flexible shaft 7 having its other end made fast to a shaft 8 journaled in brackets 9 which are fastened to Shaft 8 carries a worm 10 adapted to engageA the teeth of worm-Wheel 11. The sha t 12 of worm-wheel 11 is journaled in suitable journal *boxes formed in the side walls of the casingandrcarries a helix 13 .wound thereon and constrained torevolve therewith.

.Helix 13 is provided, upon its periphery, Wlth suitably spaced, radially extending teeth or projections 14, for a purpose hereinafter fully set forth. Y e

A grooved wheel or trolley 15V rests upon the periphery of the helix 13, said wheel being revolubly and slidably mounted on a in or shaft 16 carried by the bifurcated en' 17 of arm 18 ofv a 'bell-crank lever fulcruined at 19 to a bracket or `support 2O .carried by the casing. The other arm 21 of said bellcrank lever terminates in a clutch throw- ,ing member 22 which engages, by sliding contact, one member or platev 23 of a clutch.

Said bell-crank lever is held in normal posi` tion by any suitable means but preferably by a resilient member or spring 241 one end of which is made fast, through an e e therein, to ear 25 carried by arm 18; t e other end of said spring being fastened to the eye of screw 26 which passes through a suitable recess formed in a bracket 27 carried by` the casing, said screw permitting of adjustment of the tension of said spring by the thumb nut 28 which engages said screw.

As will be readily seen, when motionis imparted to the helix 13 through the worm arid worm-wheel7 the trolley l5 will ride on the periphery thereof, sliding along pin 16 as it travels. When said trolley comes in contact with 'one of the teethhll, it will be lifted, thereby operating the bell-crank Alever and throwing plate 23 of the clutch,

for-.a purpose which will hereafter appear.

Shaft 8 carries a clutch member, or plate, 29 which is retained upon said shaft by the collar 30 against which said plate is held by the lresilient member orspring 31. While -the clutch membcrv29 is free to slide upon shaft 8, it is constrained to revolve therewith by the key 32. l

Clutch member 23 is slidably mounted upon one end of a shaft 33 with which it is .constrained to revolve by the key 34. Said .shaft 33 is journaled in a bracket o1' support 35 carried by the veasing, and carries on its other end a bevel-wheel 36 adapted to engage bevel-wheel 37 'carried by a shaft 38. Shaft 38 is further provided, at on Patented reo. e', reis.

near its extremities, with bevel-Wheels 39 and 40 adapted to engage the bevel ends of rollers 41 and 42 respectively. Said rollers 41 and 4 2 are carried on shafts having their ends journaled in suitable journal boxes formed in the casing.

Rollers 41 and 42 are provided around the surfaces thereof With suitably spaced, radial projections or spurs 43 and 44 adapted to engage spaced recesses 45 'formed near the edges of a band or belt 46 which passes over said rollers 41 and 42 and is Wound upon drums 47 and 48 mounted upon shafts 49 and 50, respectively, the ends of said shafts being journaledI in suitable bearings carried by the casing. l V

Carried by shafts 49 and 50-'and adjoining the drums 47 and 38' are the oppositely disposed cones 51 and 52, connected, by a flexible, resilient member of any suitable "form and material, but preferably composed..

of a cable 53 having interposed` therein the coiled spring 54. n As will be readily under*l stood, said cable acts as a driving means be-,

tween the drums, the resilient member 54 tending'to preserve the .proper tension at all- Y u .portioned and thetpositions ofthe teeth on times and the oppositely disposed cones, upon which said cable Winds, acting to compensate for the change'in diameter ofthe drums due to the untvinding, of the belt from one and its Winding upon' the other.

Belt 46 in passing over rollers 41 and, 42, is guided before the indicator face 55 formed in the casing and, as said belt car- .ries upon its surface the street or station names desired, the same are successively shown, as will be described.

A crank 56' is provided at position o be t'46 should the same become desirable.

'A push button 57, adapted to extend through the casing, is carried on one en 'of the rod 58 the other end of which ispiv-V otally connected to one arm 59 of abellcrank lever fulcrumed at 60 to a suitable support 61 carried by the casing. Clhe other arm 62 of said bell-crank lever terminates a clutch engaging member 63 which is in sliding engagement with clutch member 2 9.. The'purpose of said push button 57 and its connectionthrough the bell-crank lever With belt setting, an extension or rod 64 provided at its outer extremitylvvith a knob or clapper 65 is' carried by arm 21 of the bell-crank lever, and a bell 66 fastenedto a suitable support carried by the casing is so placed as to be struck by said clapper upon the inleveone end of shaft I j 38 for the ur ose of manually adjustingthe ideare@ ment of said bell-crank lever due to the trolley 15 riding upon one of the' teeth 14 of the helix 13. A

rlhe operation of ,the device is as followsz-The driveevvheel v f6. -being in contact with the rail, is revolvediwhen the car is in -motion, imparting revolution throughits axle 5 and flexible shaitl'fto shaft 8 and Worm 10. Worm 10, through engagement vvith vvvorm-vvheel 11, Vimparts motion to helix 13. through a .suicient arc to `bring trolley 15 inl contactvvith a tooth 14,. vthe vtrolley is lifted, thereby lifting the end of arm 18 andcausing ath vv of end `22 of arni 21;

V/this causes clutch'member 23 .to` be thrown into engagement With clutchQL-'nember 2Q,A

, It Will of course be understood that the .7,

drive-Wheel, Worm and wormevvheel are proa the helix are regulated by the road on which the device is to be used andthe distance be tween stations or stops thereon. y

Having vdescribed. my invention, Whatlt cla-ini as new and desire .to secure by Patent, is
